Ashes 2013: Kevin Pietersen tests the pain barrier to prove his fitness for third Test

Kevin Pietersen was put through a series of rigorous training exercises to prove his fitness for the third Test. He was accompanied for most of England's session by the team physiotherapist, Craig De Weymarn.

The close attention showed both the management's desire to do everything they can to ensure Pietersen is ready to take his place at No 4 in the batting order and the intention to take no risks. Pietersen has been receiving intensive treatment on a calf strain which he suffered during the second Test victory at Lord's.

He arrived sporting a bandage on the calf and gingerly went through some initial routines before batting, when he did not seem in particular discomfort. After the net he did some gentle running on the outfield accompanied by De Weymarn and then team masseur Mark Saxby.

Pietersen appears determined to play, although James Taylor is on standby. He has said in the past that he is prepared to go through the pain barrier to represent England and he may have to do so yet again.
